Cesar Chavez led the historic non-violent movement for farm worker's rights and dedicated himself to building a movement of poor working people that extended beyond the fields and into cities and towns across the nation. In 1962, he co-founded the National Farm Workers Association, which would soon after become the United Farm Workers. When Filipino American farm workers initiated the Delano grape strike on September 8, 1965, to protest for higher wages, Chávez eagerly supported them. The strike lasted five years and attracted national attention. In the early 1970s, the UFW organized strikes and boycotts to protest for, and later win, higher wages for those farm workers who were working for grape and lettuce growers. His press conferences in Seattle in 1974 were part of a series of nationwide appearances given by Chavez in an effort to rally support for the UFW.
